Numerical Study of the Influence of Internal Blast on the Earth Covered Composite Arch

Abstract:

This paper presents a numerical study of earth covered composite arch subjected to internal blast load equaled to 6,25 tons of TNT. The concrete arch was protected against the blast by the 4 or 7 mm corrugated sheet. There was also one simulation where no sheet was applied. It was found that the presence of the corrugated sheet anchored to the arch can reduce 40 % of arch damage compared to the unprotected arch.
